Patent GB-340614-A (GB)
Abstract: 340,614. Cables. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Shanklin, G. B.; 109, Union Street, Schenectady, New York, U.S.A.) Oct. 4, 1929, No. 30165. Convention date, Oct. 4, 1928. [Classes 36 and 38 (i).] In a system of oil-impregnated cables in lengths inclined to the horizontal having spaced expansion reservoirs for the oil the initial reservoir pressures at the lower levels are made such as to balance the hydrostatic oil pressure in the cable lengths between each reservoir and the one next higher in the run; also where oil flow-stopping joints are used to divide the cable into sections additional partial flow-stopping joints may be used between the stop joints, expansion reservoirs being connected to the cable at one or both sides of the partial stop joints and having initial pressures such as to maintain substantially equal oil pressures on opposite sides of the partial stop joints. A reservoir and partial flow-stopping joint are shown in Fig. 2 applied to a cable having continuous oil channels 19 beneath the lead sheathing. The joint comprises a casing 14 secured at each end to the cable sheath and having dam-rings 18 which allow the oil to pass from one section of the cable to the next only by slow seepage through the cable insulation. Thus, in the event of a burst in the sheathing the oil leakage is maintained slow enough to allow detection and repair. The reservoir consists of a casing 26 sealed at its ends and containing a number of thin-walled oil cells 29 with wedgesection spacing rings 31 through which the cells are connected to the manifold oil pipe 30. The space above and around the cells is fitted with a gas or other elastic fluid under pressure which is applied through a filling valve 32. Fig. 1 shows the application to a cable run having inclined portions and limited by absolute oil stop joints 1, 2. Each length terminates in a partial stop joint 9 .. 13 with expansion reservoirs 20 .. 25. The initial pressure in the highest reservoirs 22, 23 is set, for example, at or about atmospheric pressure when the cable is cold. That in reservoir 21 is initially set at a value equal to the pressure in reservoirs 22, 23 plus the head of oil between the levels 10, 11 ; that in reservoir 20 is made equal to that in reservoirs 22, 23 plus the oil head between levels 9, 11 and so on. Thus, there is no tendency for oil to pass through the partial stop joints either normally or with changes of temperature. Two reservoirs may be fitted to each joint, one at each end, and for long lengths intermediate reservoirs also may be used, tapped directly into the cable sheathing. In the case of " solid " insulated cables without specific oil channels, the oil dams 18, Fig. 2, are not needed as the porous insulation of the cable acts as a partial stop joint.

Title: Improvements in the preparation of polyvinyl chloride
IPC: C08F259/04
Filed: 1954-11-29
Abstract: Polyvinyl chloride suitable for plastisols and of average particle diameter in the latex state of from 0.45 to 1 micron, is made by polymerizing vinyl chloride in an aqueous medium in the presence of polyvinyl chloride seed particles of smaller diameter than those desired, a water-soluble peroxygen catalyst, and a dispersing agent selected from di-esters of sodium sulphosuccinic acid in which the esterifying groups each contain from 5 to 12 carbon atoms and tri-esters of sodium sulphotricarballylic acid in which the esterifying groups each contain from 5 to 12 carbon atoms, which is added to the reaction mixture after polymerization of the vinyl chloride has commenced, at a rate such that the coverage of dispersing agent on the surface of the growing polymer particles is maintained between 90 and 375 per cent of that quantity which would theoretically be required to cover the surface of the polymer particles with a closely packed mono-molecular layer, and when polymerization is complete or terminated, recovering the polyvinyl chloride, e.g. by spray-drying or coagulation.  Two equations are given for calculating the weight of dispersing agent theoretically required to cover the polymer surface with a closely packed monomolecular layer.  Specified dispersing agents are diamyl, dihexyl and dioctyl sodium sulphosuccinates, tri-(2-ethylbutyl) sodium sulphotricarballylate and di-(2-(p-tert.-butylphenoxy) ethyl) sodium sulphosuccinate.  The water-soluble catalyst may be potassium persulphate.  In examples plastisols are made by dispersing the polyvinyl chloride in dioctyl phthalate.
